I My invention relates .to improvements in anti'creeper rail and-t1eplate construction for railways. a

-Tlre-1nain object of the inventionis to provide ail-improved rail and tieplate con- Ill structi'on, whereby creeping ofthe rails on the cross ties, on any grade or under any load is prevented.

Further to provide a tie plate having a 1 plurality" of u-pn-ardly. projecting; parallel teeth or ribs, and a rail havingcorresponding recesses formed .in-itsbzise flange to receive said teeth or ribs, the tie plate being also formed with spi-kereceiving apertures, whereby,when the rails' a-re laid upon the platesand spiked to the cross ties, the heads of the spikes engaging the rail flange in the usual manner, ,theplat'es are thereby :immovably secured to the ties and the rails are clamped against the plates, theteethof the plates engaging the .c'orresponding r'ecessjesin the rails, thus preventing creeping of the rails under any conditions of load or grade. These, objects are accomplished by the construction embodied in the accompanying drai'vings in "which,

Fig. 1 is avertical transverse sectional viewthrough a rail and tie plate constructedin accordance with my invention,.said rail and plate being spiked to a cross tie. 1 Fig. 2 is a longitudinal sectional View through the -plate andth'e-[base portion of the rail.

Fig. 3 is a perspective view of the improved tie plate, looking at. the upper side thereof.

Fig. 4: is a perspective view of the tie plate, looking at the under side thereof, and Fig. 5 is a bottom plan view of a portion of a rail embodying the improved construction.

In the present practice of track construction for railways, the tracks or rails rest either directly upon the ties or upon metal plates which are placed on the ties, and are secured to the ties by spikes which pass through holes in the plates, the heads of the spikes engaging the rail flange. Such method, however, permits creeping of the rails under the rotary action of the car wheels, particularly on heavy grades, or under the frictional engagement of the wheels with the rails when the brakes have been applied, whereby the fish plates connecting the adjoining ends of the rails are frequently an inch hi 'h.

broken thus permitting the connected rails to be drawn apart or disconnect-ed. "The" construction embodiedinthe presentapplication, however, positively eliminates this disadvantage by providing alocking conned tion between the rails a'ndthe tie plates, as Q tically disposed ribl, which 'eiiteiid's the full,

width of the plate and is about a fourth or 'The inner face jof t-hi'srib forms anii' butmeiit shoulder for one edge of the rail flahge, and from this shoulder the upper face-of th'e plat'e ms asl-ight down ward inclination't'o its opposite end edge, as clearly shown in Fig. 1'. The outersid'e of the rib inclinesdown to the face of the plate, as shown, from which point the face of the plate has a slight down inclination to the adjacent short e'dge.-

pl'uralit'y'iif longitu'din'ally dispdsed teeth'or projections '2 are formed on the upper face: of the plate and midx vay of its length, these teeth being Jenthe 7 tively longand'of greater widthrtha Y spaces between them. They are preferably rounded; intransverse sectional outline and their ends are beveled-at an angle to the face of the plate. Transverse grooves or channels 3 are formed in-the face of the plate adjoining the ends of the teeth 2, and square spike-receiVing holes 4 and 5' are formed through the plate, the holes 4 being cut through the abutment rib 1 and so that the inner faces of the said holes are inside the line of the inner face of the rib, as shown most clearly in Fig. 3. The channels 3 are to receive any dirt or grit that may collect between the teeth of the plate and the rail grooves, and carry it off.

The under side of the plate is formed with two transverse parallel shallow channelsh and the end portions of the plate are reduced in thickness as shown at 7, and the channels 6, and the reduced thickness 7 define three flat parallel bearing faces 8, 9 and 10, the middle face 9 being of less width than the faces 8' and 10, and these faces become slightly embedded in the tie under the weight imposed upon the plate and the plate is thus more evenly seated on the tie than, would be the case if the bottom of the plate were perfectly flat. In connection with the improved tie plate above described, I employ a railv 11, which in all respects is identical with rails in present use with the exception that the bottomcface of its base flange is formed centrally of its width with' transverse grooves or recesses '12 to receive the teeth or ribs 2 on the he plate. These grooves 12 are rolled into the rail in the process of its 'manufactutre, and extend throughout the length of the rail and are slightly longer than the teeth 2, their ends being inclined to, correspond to the inclined ends of-the said teeth 2. The ends of the rails are cut by gauge orso that when the ends of two railsjoin on a tie plate there will be no break in tie continuityvof the grooves 12, and the two rails will join and lit down on the teeth The inclined 2,,the same as a single rail. 7 upper faces of the track plates will cause the two rails to incline slightly toward eachother, as will be understoodby reference to Fig.1, I

In practice the tie plates are placed upon the ties, and the rails are then laid upon'the tie plates-so that the teeth on the plates engage the grooves in therails; Spikes 13 of it the usual type are then driven through the quences due "to such an accident, together with the time and expense necessaryin repairing such damage.

Having described my invention, What I claim as new and desire to secure by Let-v ters Patent, is M I .1. In mechanism of t-he character described, the combination of a tie, a tie plate thereon,.having spike receiving apertures, a

row of elongated teeth, parallel channels ad-- joining the ends of said teethand an abutment rib; and a rail resting on said plate and against said abutment rib, spikes driven through the holes in said plate to secure the plate to the tie and the rail upon the plate, said rail having grooves to receive said elongated teeth, whereby creeping of the rail 0 the plate is prevented.

2. As a new article of manufacture, a railway tie plate provided on its top side with an abutment rib,'a row of elongated teeth extending at right angles to said rib, parallel channels ext-ending respectively along the 1 ends of said teeth, and spike-receiving holes, in combinatlon with a rail having spaced lelongatedflgrooves in its base flange to re- (3B1VG-S2Lld. teeth, when the rall lSlEllCl on said:

plate and against said abutment rib, whereby endwise movement of the trail on the plate is prevented. I

3. A rallway tie plate having a central row of pro ecting teeth, channels being formed along the ends of the teeth, an abutment rib extending. at right angles to "said teeth, and raised bearing surfaces on the bottom ofsaid plate, said plate having pairs of spike receiving holes, one pair of said holes being cut through said abutment rib.

In testimony whereof, I aflix-my signature.
